The Client: data-driven solutions for real estate market analysis

Eltinga specializes in real estate market analysis, delivering innovative, data-driven solutions tailored to client needs.
Its clients include developers, investors, and public institutions seeking reliable information and decision-making tools grounded in accurate analysis and statistics. Backed by a team of experts in economics, geography, and data analysis, Eltinga offers personalized services designed to meet each client’s unique requirements.
The company places a strong emphasis on the quality and accuracy of its analyses, ensuring that clients can trust the data for project planning and property value assessments. Partnering with Eltinga provides access to the latest market trends and advanced tools to support the growth and success of real estate investments.
The Problem: creating a robust and flexible tech solution in a month
Eltinga faced the challenge of developing an online platform: a tool designed to help property owners easily and intuitively assess the potential for energy efficiency upgrades to their buildings.
Although the team had extensive experience in energy analysis, they lacked a robust yet user-friendly tool capable of fully automating the process. Such a tool needed to enable users to quickly estimate the benefits of upgrades like improved insulation, window replacements, or heating system enhancements. Adding to the complexity, the tool had to be developed within just one month (!) and required the flexibility to accommodate rapid and frequent changes. This included updates to the site structure and modifications to the algorithms calculating energy efficiency, as the project had to adapt to evolving requirements from government institutions and banks collaborating with the client.
Eltinga needed a partner who could not only deliver the final product in record time but also advise on technology selection, understand the complexities of energy processes, and meet their customers' needs. Specifically, they required a partner who could:
01
Provide a flexible technology solution quickly
The client needed a tool that is accessible to users, automates the process of assessing building energy efficiency, and allows for rapid implementation and easy updates.

Further development and scalability
We plan to further enhance the Eltinga tool by integrating it with external databases beyond the Bubble.io ecosystem to achieve greater flexibility. Additionally, we intend to develop an advanced computational algorithm outside of Bubble.io to improve the application’s performance and fully utilize Eltinga’s sophisticated analytical models. Bubble.io will continue to serve as the frontend, enabling rapid updates to the visual design and user experience.
Conclusion
We developed a fully functional web platform for Eltinga in just one month using the low/no-code Bubble.io platform. This approach saved the client 115,000 PLN in MVP implementation costs and reduced monthly operating expenses by 47,800 PLN.
The solution is scalable, flexible, and designed to accommodate rapid changes required by customers and business partners. It also supports seamless integration and future development.
